您好，我是使用 nginx 的初学者。我的网站已启动并正在运行，目前它将 http 重定向到 https。但是，如果我访问www.example.com，nginx 会将其重定向到https://www.example.com。我怎样才能让 www 被重定向到 https？

我的 nginx 配置如下：

    server {
        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;
        server_name _;
        location / {
                try_files $uri $uri/ =404;
        }
}

upstream my_nodejs_upstream {
 server 127.0.0.1:5000;
 keepalive 64;
}

server {
        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;
      server_name example.com; # managed by Certbot

        location / {
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection upgrade;
                proxy_max_temp_file_size 0;
                proxy_pass http://my_nodejs_upstream/;
                proxy_redirect off;
                proxy_read_timeout 240s;
        }

        location /api {
                proxy_pass http://localhost:3001;


    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80 ;
        listen [::]:80 ;
    server_name example.com;
    return 404; # managed by Certbot


}

【解决方案1】：

要做的事情是实现http -> https重定向在www。

将 www. 添加到服务器块中的服务器名称，如下所示：

server_name example.com; # managed by Certbot

到

server_name example.com www.example.com; # managed by Certbot

确保 www. 的 A 记录（如果不可用，则创建子域 www.）从您的域的 dns 指向服务器的 ip。
为新的服务器块重新生成证书。

现在您可以将 http:// 和 http://www. 重定向到 https
